Answer:
1. CO₃⁻² + H₂O ⇄ HCO₃⁻ + OH⁻
2. HCO₃⁻ + H₂O ⇄ H₂CO₃ + OH⁻
3. H₂CO₃ → H₂O + CO₂
Basic solution
Explanation:
Brønsted Lowry theory:
Acid → Release a proton
Base → Accept a proton
1. CO₃⁻² + H₂O ⇄ HCO₃⁻ + OH⁻
Carbonate takes a proton from the water
2. HCO₃⁻ + H₂O ⇄ H₂CO₃ + OH⁻
Bicarbonate takesa proton from the water to produce carbonic acid.
3. H₂CO₃ → H₂O + CO₂
Carbonate acid decomposes into CO₂ and H₂O
In the first reaction, when the carbonate takes a proton from the water, water releases OH⁻, so the solution is basic.
Answer:
A small amount of solute dissolved in a larger amount of solvent.
Take this analogy to help you understand, if you were to put a teaspoon of sugar in a liter of water it would dissolve, but if you put a sack of sugar in it it would not dissolve! The solute is what is being dissolved and the solvent is what dissolves the solute, so that eliminates some of the options.
<span>Answer:
.01 moles of D to .005 moles of L ~ so, .01+.005 = .015 total; using this total value, divide the portions of D and L.
so .01/.015 to .005/.015 ~ 67% D to 33% L.
And thus, the enantiomer excess will be 34%.</span>
